Implementation model of the production process control system at a car service enterprise

Due to the different structure of the technical service of motor transport enterprises (MTE) small, medium, large capacity and volume of maintenance work and repair of vehicles, can provide the same competition conditions in the transport market. As follows, the main task when solving the question satisfaction of demand for maintenance services and repair of vehicles is the use of existing production facilities MTE АТP of different departments, that is, transformation of departmental production infrastructures into a regional structure is needed. Using the proposed method for specific conditions of motor transport enterprise (MTE) will allow based on the numerical value of performance evaluation criteria for maintenance and car repair determine the rational structure of it production and technical base (PTB). This is accordingly, will increase the enterprise efficiency, optimizes PTB and help to identify perspective directions the interaction of transport enterprises and centralized specialized productions for the maintenance and car repair. The article provides the determining method the expediency of creating or maintaining production units for maintenance and cars repair in motor transport enterprises. Object of study is the formation of the production units’ structure in the motor transport enterprises, depending on the volume of maintenance and repair works. The aim of the work is to increase the efficiency of motor transport enterprises by improving the production departments structure for maintenance and car repair. To achieve the goal in the framework of the work performed, the following research methods were used: analysis of processes and phenomena, hypothetical method, mathematical modeling of processes, mass observation, data statistical processing of the experimental research results. Terms creation of one or another unit for maintenance and cars repair in the enterprise is a minimum of reduced costs, in which the implementation of a specific type of work is economically appropriate at the specified enterprise. If it is inappropriateness of creation any of the subdivisions, the corresponding works are transmitted for implementation at the nearest ATP, stations of cars maintenance (SCM) or other enterprise where these services are performed. The method of efficiency estimation of production units for maintenance and cars repair in motor transport enterprises is developed, which allows to make calculations for ATP of different capacities.

The paper proposes a working hypothesis that, in order to ensure competitiveness in the market of transport services, the structure of production units of motor transport enterprises should be determined by the volume of maintenance works and repair of vehicles, taking into account the economic criteria for the cost of implementing the service unit. When determining the expediency of creating production units for maintenance and repair of automobiles in motor transport enterprises the cost of a 1-man-hour of work on maintenance and repair of vehicles was found out. It should be noted that the cost of maintenance and repair of vehicles depends not only on the volume of work, but also on the cost of technological equipment, the required area, the number of workers, qualifications, their wages and other factors. With the increase of volumes of works (and there was a lot of work) on maintenance and repair of cars, the cost price is gradually decreasing, which is associated with an increase in the load of personnel, process equipment and more rational use of production space. On the basis of the cost price of the 1 st man-hour, the minimum volumes of work are determined, in which it is expedient to perform specific types of maintenance and repair works and to create the appropriate production units in the motor transport enterprises. The minimum volumes of maintenance and repair of cars are established by comparing the cost of performing works in a motor transport company with the cost of performing these works at the car service enterprises (and it was in service centers). The cost of delivery of cars and repair fund in service centers is determined, which accounts for 1 man-hour of labor-intensive maintenance and repair work. On the basis of the estimated delivery cost, the economically feasible radius of maintenance and repair of cars was determined on the basis of co-operation in service centers. The hypothesis that, in order to ensure competitiveness in the market of transport services, the structure of production units of motor transport enterprises should be determined by the volume of maintenance works and vehicle repair, taking into account the economic criteria of the cost of the service unit, quite adequate.

Based on the analysis of the functioning of the production process of the enterprise and studying the experience of planning, regulation, evaluation, analysis of the quality of services for maintenance and repair of cars, the effectiveness and efficiency of the production process of enterprises, it is shown that for effective management of the quality of processes, a detailed study of all components of production processes and factors that they are influenced by interdependencies between them. The possibility of managing the quality of services for the maintenance and repair of vehicles and the efficiency of their production using neural network modeling, which can be based on the mathematical Markov model of the production process based on two-layer neural networks, makes it possible to simulate the relationship between service properties, characteristics and factors of the production process. It is shown that the process of car maintenance and repair can be represented as a set of end-to-end neural network control and forecasting models, such as a model for studying and forecasting the development of the service market; model of quality management and efficiency of energy resources, spare parts and materials for maintenance and repair; management model of the general technology of maintenance and repair of units and the like; A scheme for determining generalized indicators of the quality of maintenance and repair of vehicles has been developed. For example, one of the auto service enterprises considered the possibility of using neural network technology to assess the quality of services and the efficiency of the production process.

The use of model‐based methods to support planning, designing, and operating chemical processes and plants has recently gained an increased importance in the daily work of process engineers. The development of mathematical models through the use of standard flow sheet simulation tools requires the expertise of an experienced designer. Therefore, the value of existing models is not limited to the resources required for their development, but also includes value in the form of knowledge about an enterprise's products and production processes. The reuse of existing models and design experiences in order to lower the costs of model development is therefore economically desirable. This report gives an overview of the systematic long‐term management and use of mathematical models. Some motivating scenarios are used to derive the requirements for a model management system and to evaluate existing methods and tools. The results of these example scenarios are then used to guide the development of a model management system. After presenting a prototypical implementation the article concludes with an outlook on the future importance of model management systems.

The article describes a method of rational organization of maintenance and repair of light commercial vehicles of foreign production using specialized diagnostic tools with the diagnosis in cooperation with branded service stations (BSS). The main purpose of using technical diagnostics tools is to reduce the time losses that occur when sending vehicles for maintenance, and to reduce the cost of maintenance and repair of foreign-made trucks undergoing maintenance and repair at a motor transport company (MTC) and at branded service stations. A simulation model is used as a tool for assessing the economic efficiency of various options for cooperation between a motor transport enterprise and a branded service station when performing maintenance and repair of light commercial vehicles of foreign production. The objective function of the simulation model contains components that estimate the loss of profit from the downtime of vehicles in the maintenance and repair area and the cost of organizing maintenance at the enterprise in cooperation with the company’s service station. A comparative analysis of each variant of the organization of cooperation is carried out with and without taking into account the use of diagnostics. The currentness of the described methodology is explained by the fact that in the field of production of services for maintenance and repair of light commercial vehicles, fundamental changes have occurred, caused by a change in the form of ownership of both transport enterprises and maintenance and repair enterprises. In addition, the widespread use of foreign-made light trucks has led to the emergence of branded service stations that have licenses to service and repair foreign cars during the warranty period. This circumstance fundamentally changes the scheme of servicing these vehicles and increases the downtime of expensive foreign-made cars for organizational reasons.

The study's abstract summarizes the findings of years of research in the area of quality management of industrial production and construction production, which were based on mathematical modeling techniques, process, and outcomes of implementing the developed program of monitoring and quality control in the enterprise's production process. The objective of this work is to show to the scientific community the useful outcomes of mathematical modeling in software applications. Quality control and safety represent increasingly important concerns for project managers. Defects or failures in constructed facilities can result in very large costs. Even with minor defects, re-construction may be required and facility operations impaired. Increased costs and delays are the result. In the worst case, failures may cause personal injuries or fatalities. Accidents during the construction process can similarly result in personal injuries and large costs. Indirect costs of insurance, inspection and regulation are increasing rapidly due to these increased direct costs. Good project managers try to ensure that the job is done right the first time and that no major accidents occur on the project. The research focused on describing applicable mathematical models, viewpoints, and practical outcomes of their use in the applied sector to evaluate quality control. This mathematical model was applied by the authors. The outcomes of using this approach are presented in the article. By utilizing mathematical modeling techniques, the authors created an experimental software management and quality assessment system. The authors continue their study in this area to enhance prognostic and diagnostic processes based on mathematical modeling methodologies for diagnostic systems and quality management systems.. The independent quality control, which was based on some traditional inspection techniques and used mathematical modeling techniques, revealed a negligible partial discrepancy in the results of the estimation, proving both the efficacy of the product and the suitability of the mathematical modeling concept. Keywords: Quality control, mathematical modeling, construction quality.

In recent years, with the rapid growth of China’s automobile ownership, the profit proportion of automobile aftermarket in the automobile industry is increasing day by day, and the automobile service industry is gradually growing in the development of China’s national economy. The current automobile maintenance management software is not good and bad, most of these management software in order to meet the common possible user needs and lead to the same software function, lack of consideration for the management system of small and medium-sized enterprises, and there are certain defects in generality. At the recent 2020 China Automobile Supply Chain Conference, Wu Wei, director of the Machinery Department of the Industrial Development Department of the national development and Reform Commission, said that the production and sales volume of the automobile market had achieved a year-on-year growth for six consecutive months. If this momentum can continue in the fourth quarter, the total production and sales volume by the end of this year is expected to be close to the level of last year. Automobile fast repair refers to the activities of automobile maintenance and minor repair, but not vehicle repair, automobile assembly repair and secondary maintenance. The service scope is locked in 120 fast repair and maintenance items that can be completed within 2 hours. At present, the total number of motor vehicles in our country is huge, and the number of maintenance enterprises can not meet the demand of maintenance, so the potential of automobile fast repair market is unlimited. As the main business of fast repair industry, automobile fast repair is paid more and more attention by people. The application of digital management mode and maintenance cases creates good conditions for the development of fast repair enterprises, and makes it possible for fast repair enterprises to adopt reasonable maintenance methods. This paper focuses on the chaos in maintenance management, On the basis of the research and analysis of automobile maintenance management system and digital management concept, taking customer demand as the starting point, this paper designs a digital automobile maintenance auxiliary system specially for automobile fast repair enterprises to assist managers in maintenance management, so as to achieve the purpose of standardized management business “fast and reasonable” maintenance, and improve customer satisfaction.

The aim of the article is to propose the main characteristics of the new generation of breakthrough technologies in the system of maintenance and repair of vehicles and to generalize the description of the controlled processes occurring in vehicle systems. The use of structural synthesis has allowed us to offer the basic characteristics of breakthrough technologies of a new generation in the system of maintenance and repair of vehicles. The technologies of the new generation are characterized by the optimal one due to the main features (or properties), vehicle features and maintenance system. To create innovative technologies of a new generation, it is necessary to provide unconventional support (a highly qualified level of personnel, a progressive level of a technical system, a technological level of the environment) and use complex systems of diagnostics, control and equipment management for maintenance and repair of automobiles. An integrated approach allows the use of non-traditional technical and economic indicators (total cost of expenses for all objects of the hierarchy level of the macrosystem, the cost of the life cycle of units, nodes, the cost of the costs of material, energy and information activities). Changing the technical condition and monitoring the performance of vehicles can be represented in the form of a system at the input of which there are vector functions: operating conditions, management of the maintenance and repair system, internal communications of the control system. As a result of modeling changes in the technical condition, a state function is obtained that gives a generalized description of the controlled processes in vehicle systems. The state function of motor vehicle aggregates may include deterministic (clear and unambiguous) and random components.
